Question 1#

Which of the following is INCORRECT concerning the anatomy of the penis?

a. The paired corpora spongiosum functions as one compartment due to vascular interconnections
b. Priapism is defined as a persistent erection of more than 4 hours' duration
c. The corpora cavernosum are enclosed by the tunica albuginea
d. The corpora cavernosum and spongiosum are surrounded by Bucks fascia

Correct Answer is A


The corpora cavernosum are the paired, cylinder-like structures that are the main erectile bodies of the penis. The corpora cavernosum consist of a tough outer layer called the tunica albuginea and spongy, sinusoidal tissue inside that fills with blood to result in erection. The two corpora cavernosum have numerous vascular interconnections, so they function as one compartment. Surrounding all three bodies of the penis are the outer dartos fascia and the inner Buck fascia.
